MY TRUCK TURNED OFF WHILE PROGRAMMING AND NOW IT DOES NOT START/AN ERROR KEEPS APPEARING, HOW DO I FIX THIS?

 

Important: If the AutoCal's programming process is interrupted due to power loss, it may result in a corrupted PCM.

How to Prevent This Issue

To avoid issues during programming, ensure that:

  • The vehicle is connected to a battery charger providing at least 10 amps of continuous power.
  • The ignition remains in the ON position throughout the programming process.

Steps to Fix the Issue

  1. Check the vehicle’s battery and connect a charger if needed.
  2. Attempt to reflash the vehicle using AutoCal.
  3. If a VIN error appears, the vehicle must be restored to its stock settings before proceeding.
  4. Note: We do not provide stock tune files. If needed, this step must be performed at a dealership.
